摘要： PROBLEM TO BE SOLVED: To provide a printing device, wherein the rush-in temperature of a web to a fixing device is stabilized by keeping a quantity of heat applied to a web constant at the start of and during printing. SOLUTION: Temperature sensors for detecting the temperature of a preheater are disposed in two areas of upstream and downstream areas, of a preheater. At the start of printing, the temperature of the preheater is controlled by use of the upstream temperature sensor, thereby suppressing undershoot. In addition, during the printing, the temperature of the preheater is controlled by use of the downstream temperature sensor of the preheater, thereby stabilizing the temperature of the web rushing in the fixing device so that it reaches the temperature required for fixing.
